Abstract
A mechanical device that has the ability to manage and set explosives cones in the rocks that form the hanging, which can be operated remotely, avoiding the danger of the current state of the art where operators place explosive using bamboo sticks, before detonating them, causing an imbalance in the hanging. The mechanical device also known as cone-holder, is located at the end of an automated and semi autotransportable manipulator arm for releasing hangings.
Claims21
A device for carrying, handling and placing an explosive cone for the release of overhangs in underground mines, attachable to a semi-automated handling arm, the device comprising:
- a gripping system for the explosive cone including at least one of pneumatic cylinders with penetration points, tweezers with spike like penetration elements, or a gripper system for gripping the surface of the explosive cone;
- a support plate coupled to the gripping system;
- a fitting spring positioned between the gripping system and support plate;
- two pneumatic thrust cylinders configured to extend the gripping system;
- a pneumatic motor for rotation configured to rotate the gripping system;
- a pneumatic motor for inclination with a endless screw and crown system, the pneumatic motor for inclination being configured to adjust the inclination of the gripping system;
- a joint support for securing the gripping system to the semi-automated handling arm;
- and
- a protective cover covering the pneumatic cylinder and the pneumatic motors.
